High-performance insulation materials, disinfectant wipes and supply chain transparency – Kelheim Fibers present solutions at Techtextil in Frankfurt. Kelheim’s dry short cut viscose fibers contribute to energy saving: Fibers with an extremely fine titer are processed along with pyrogenic silicid acid to vacuum insulation panels (VIPs). Viscose fibers contribute to reinforcement and allow for permanent dimensional stability. VIPs offer the same insulation effect as rock wool with only one tenth of the thickness. Such panels are used for example in refrigerators and freezers, as well as in building insulation. Transport logistics that demand an uninterrupted cold chain is another promising future market for these special fibers.

Fresh from Kelheim’s R&D laboratory is the new viscose special fiber, Danufil QR. It is specifically designed for use in disinfectant wipes. While standard viscose fibers, due to their negative ionic charge, bind up to 80% of “quats” (quarternary ammonium compounds, a common disinfectant) and so hinder their actual purpose, the positively charged Danufil QR fiber can reduce this undesired effect to less than 10%. Danufil QR also scores with its softness, excellent fluid management and full biodegradability.

Supply chain transparency and protection against forgery is another topic addressed by the viscose fiber experts: A marker fiber enables the – invisible for the human eye, but definite and even customer-specific – encoding of products. So, the traceability of a product can be guaranteed, and customers and manufacturers can be protected from possible economic damages by plagiarism.
